Rear air gauge acting up on American Coach

[S. Kerstetter]

I have a 2005 American Tradition on a FL XC chassis and the rear air pressure gauge just sweeps back and forth. I know the air pressure is fine and there are no leaks. I traced the red and green airlines into the dash where they go into the back of the warning light cluster. Front pressure gauge works fine but rear just sweeps back and forth whether you have driven 1000 miles or just started it up. Any ideas.

Try this and see if it is the same problem
Air problem, location of VDC?

Welcome to IRV2. As Mike has noted, several here, myself included, were able to resolve a similar problem as noted in the thread.

Suggest you call the Freightliner help line and describe your problem. If they tell you it is your VDC (Vehicle Data Computer), I would suggest you try the fairly simple fix we describe.

Thanks. Does anyone happen to have the link to that fix?

The link is located in Mike Canter's post above.
